Use of Urban and Industrial Wastewater for Crop Production, (Year : 2016)
|
Aims and Objectives:
- Highlight the harmful / deleterious constituents in the waste water
- Give treatment for elimination of these constituents
- Recycle / reuse the waste water for biomass production
Scope of Work:
- Assessment and characterization of w/w for its suitability to use for agro-recycling
- Effective & appropriate management of w/w as a source of irrigation water
- Improvement in the efficiencies of w/w for their nutrient potential
- Evaluation of bio-remedial techniques for increasing the efficacy of w/w utilization
- Cost effective assessment of w/w irrigation practices
- Human resource development to promote the recycling and reuse of w/w for sustainable agro – ecosystem.
Summary: Land application of domestic wastewater has been adopted as one of the methods of wastewater treatment and disposal. Besides irrigation, it offers an alternative for the resource recovery from wastewater in the form of plant nutrients and water reuse through agriculture. Land application provides primary, secondary and tertiary treatment to the waste, all in a single operation with recycling and reuse benefits of water and nutrients for biomass production besides preventing the pollution of streams and lakes. Survey and periodic sampling of urban and industrial wastewater for physico-chemical and biological considerations: Site Details The project scheme is being operated at following sites
- Urban sewage/ wastewater Sugar industry (agro-based activity)
- Paper & pulp industry
- Distillery Industry in Tamil Nadu (proposed) Characteristics of Urban wastewater As per the objective of the project, urban wastewater was monitored in the city of Nagpur at three strategic locations from where the wastewater is being reused for irrigation purposes.
Nag river, which originates in the lake Ambazari, flows through the Nagpur city and carries the water from all the domestic as well as industrial sources in the city. Thus, today the river is turned into a wastewater carrying drain. Characteristically, only the part of city wastewater is treated in the sewage treatment plant and the treated wastewater is again discharged in the flowing drain. Out of these three sites, site
- receives the treated wastewater from the sewage pumping station while the other two sites are as good as for untreated wastewater. Site for urban sewage/ wastewater is selected about 12 km from the NEERI where wastewater from river Nag is available and used for irrigation purpose. The wastewater from Nagpur City is treated partially at Bhandewadi Sewage Pumping Station and disposed in the river Nag.
- It further flows to the experimental site at village Bharatwada about approx. 20 km from Nagpur. The wastewater characterization details in different seasons indicate that the concentration of pollutants are at lower profile in monsoon season due to dilution effect and high in summer. Sewage water is rich in nitrate and phosphate and are conducive for biomass production. However, the chlorides and sulphates in the sewage are also high indicating the anthropogenic influence. Seasonal heavy metal contents in sewage used for irrigation were monitored. It is observed that in general the concentrations are high in winter and summer seasons than the monsoon. Of all the heavy metals, the Ni contents are exceeding the permissible limits in all the seasons except monsoon.
- Cost effective assessment of wastewater irrigation practice using urban wastewater indicated that there is 2-3 fold increase in yield with respect to paddy and wheat. For chilli crop, the increase ranges from 8-10 fold. Cultivating aromatic plants is a new perspective, which is highly profitable when urban effluents are used for irrigation.

To study the Quantum Particulate Dispersion from Mining Activity and its Effects on Plant at Chandrapur, (Year : 2015)
|
Aims and Objectives:
- Assess the particulate dispersion from the mining and related activities
- Study the effect of dust deposition on nearby plants/crops
- Recommend mitigation options to control productivity losses
Scope of Work:
- The proposed study area will be the WCL Mining area in Chandrapur District.
- The studies will span over a year comprising of three seasons namely winter, summer and monsoon.
- The study fields will be identified for crops as well as forest trees at strategic distances from the transport activities say 5 m ( adjacent to road side ), 100m, 200m, 300m
- Depositional rate of aerosols will be monitored manually in the field as well as from modeling exercises using software package
- Evaluation of particle deposition on leaf surface
- Morphological and physiological alternations (visible and invisible) will be assessed on seasonal basis in the crops • Overall growth of the crop plants on yield basis and on carbon will be computed
- Mitigation options to control productivity losses will be suggested in the final report
- Socio-economic assessment of the study area will be carried out by third party Non-Government Organization
- Two Workshops, one at the start of the project and other at the completion of the project `will be organized
Summary: During mining operations the particles are emitted in various operations like excavations, blasting and also during the transport of the mined products. Also, mining activity generates large quantities of over burden which is nothing but the loose earth material excavated and deposited in upside down position. This loosened material is also prone to be wind blown and disperse in the atmosphere. Considering the gravity of the problem, Western Coal Fields Ltd., Nagpur has retained National Environmental Engineering Research Institute (NEERI), Nagpur to study the quantum of particulate dispersion from mining activity and its effect on plants. Assessment of impact of transportation on standing vegetation on Hadasti Ghat Route and Visapur Ghat Route was undertaken for Rabbi & Kharip crops.
The crops selected for the study were:
- Jowar - Sorghum vulgare
- Tur - Cajanas cajan
- Chilli - Capsicum annuum
- Cotton - Gossypium hirsutum Hadasti Ghat Roue is currently under operation for sand transportation while Visapur and Seoni Ghat Routes are closed for sand transportation. Samples were collected at strategic distances from the Ghats i.e. Wardha river bank as starting point up to the jurisdiction of WCL area. At each location, the samples were collected at a 5, 100, 200, 300 meter distances from the edge of the road and coded as A, B, C, and D respectively
The results of the study indicate that
- The Dust dispersion in the ambient air due to sand transport is higher in the study area than the no activity zone
- The particulate concentration is higher in summer season (maximum value of 16.2 MT/km2 / month at Charwat village) than the winter season
- Water soluble fraction of the dust is negligible and the chemical composition of dust is harmless, innocuous as there is no component in the dust which is hazardous to plant growth
- The dust deposition on the leaf surfaces of crops in Hadsti Ghat route is more than the Visapur Ghat route which is not in operation during study period
- The morphological analyses of the crop plants : Jowar, Tur, Cotton and Chilli indicate that there is no correlation in the morphological parameters and dust deposition on the leaf surfaces
- The dust deposition is more on the leaves of crops which are at the edge of the road (5 m from road side) than 100 and 200 m distances respectively
- The particle size distribution indicates that the 60 % of the road dust is of >100 micron size i.e. does not remain suspended in the air over a long period and settle down under gravitational force nearer to the source
- The dust collected in the jar has 86 % of the particles in the range of >100 micron size while 45 % of dust particles deposited on the leaf surface are in the range of > 51 to < 100 micron size
- The soil analysis shows that the soils are poor in nutrient value (available N,P,K)
- There is poor irrigation facility in the study area due to which the crops on Visapur Ghat road which is not in operation during study period show low yields than the Hadasti Ghat route
- The farmers are not managing the fields according to the standard agricultural practices which is evident from poor irrigation facility and application of inadequate organic and synthetic fertilizers which seems to be the prime cause of low yields in the region.
